The Unsung Hero is a treasure that is unlocked when the player scans the Luigi amiibo from the Super Mario Bros. series. It looks just like the amiibo, and is worth × 200.
Collecting the treasure
After scanning the amiibo on the area selection screen (in any sector), the treasure will appear in one of the Secret Spots of the area. Then, the player has to retrieve the Unsung Hero in that spot.
